With post-workout nutrition, timing is everything. If you want major mass gains, you need to take advantage of the slim—but valuable—window of opportunity immediately after workouts. Because your muscles grow while they are recovering from the workout, and not during the workout, you need to feed them with a recovery supplement specifically designed to support muscular mass production. With Mass Factor that is exactly what you get! Here is why...

Mass Factor has been designed to inject a burst of growth-stimulating protein and carbs into your muscles after consumption to feed the growth frenzy of the first stage. Then, the next wave of slower-absorbing protein gets pumped into your muscles to support the second-stage growth spurt.

This "two-stage slower-absorbing activating system" is made possible through the use of "fast" and "slow" acting proteins and carbs. A blend of whey and casein provides the perfect protein combination, because research shows that whey protein is absorbed very rapidly into the body, while casein has a delayed absorption profile. Next, a specialized carbohydrate blend is used as the exclusive carb source. Why? Becuase it provides both a short and longer chain carbohydrate molecules. Short chains are absorbed rapidly, and longer chains more slowly, feeding your muscles a continuous stream of clean carbs throughout both stages of the anabolic recovery phase.

A combination of whey and casein—post-exercise—has been shown to increase the level of muscle protein synthesis during recovery over and above a standard carbohydrate supplement.
